Erosion Control

Erosion Control and Post Construction Stormwater Management

Erosion control is the practice of preventing or controlling wind or water erosion associated with agriculture, land development, and construction activities. This typically involves the creation of a physical barrier to absorb some of the energy of the wind or water that causes the erosion. Erosion barriers include:

• Bales
• Erosion Mat
• Fences

Post construction stormwater management is required when a certain amount of impervious surface is constructed (i.e. parking lots, roofs). A plan must be created to control the discharge of pollutants and increased stormwater rate and volume that is created. Post construction BMPs include:

• Bio-filters
• Infiltration Basins
• Ponds (Wet And Dry)

Reasons for controlling stormwater:

• After construction, proper stormwater management controls are needed when impervious surfaces are built (roads, parking lots, large structures) to reduce soil and other pollutants and minimize the discharge rate and volume in stormwater leaving the site to protect wetlands and waterways.
• During construction, proper erosion controls reduce soil from leaving the construction site and contaminating wetlands and waterways to protect fish and animals and their habitat.
• Restore and enhance infiltration
